- TOC is a command for the wiki engine telling it how to handle the table of contents. Frequently its automatic selection for where to put it is in the way or inconvenient, so we frequently specify where to put it. -- Strangelv 15:28, 12 June 2008 (UTC)

Flashbulb Rocket
If I remember correctly, the circularizing velocity for the mass driver described in "FIRST MASS DRIVER" is about seven meters per second, less than one thousandth of the mission delta v for Earth to low Earth orbit. This should be well within the range of oxygen aluminum rockets that people should one day be able to produce on Luna. As for the flashbulb rocket in particular it is essentially a solid fuel pressure feed oxidizer rocket in which the exhaust gas is the excess oxygen. Igniting this rocket should be no more difficult than igniting a flash bulb. The particular fuel/oxidizer mixture that melts open the valve to the oxygen tank need not be exactly thermite. The Aluminum oxide threads coated with aluminum and or magnesium would need coatings of silicon oxide and or silicon on some to control burn rate, allow pressure build up in the combustion chamber and allow transfer of heat to the excess oxidizer. This would be a single use rocket for which the electronic timer and battery or capacitive storage device would be salvaged. Another sort of rocket might do as well. --FARTHERRED 8:10 Central daylight time
More Flashbulb Rocket
Versions of a flashbulb rocket have been suggested in which the combustion chamber would be within the oxygen tank. Both the combustion chamber and oxygen tank would be radially symmetric about the axis of rotation of the spin stabilized spacecraft. An aluminum coated glass film plug might stop up the expansion nozzle to prevent sunlight from entering the combustion chamber before ignition. A pressure relief valve would maintain temperature in the insulated oxygen tank. --Farred 03:41, 27 October 2008 (UTC)
